Property [id] does not exist on this collection instance

[marsh hill]

when I print the dd I have the id, but when I try to use it, it gives the error.

public function LoadcalculoSeguro(CalculoSeguroService $calculoSeguroService){
    if (!empty($this->atividadeCode))
    {
        $this->precos=$calculoSeguroService->getPrecos($this->atividadeCode);
       // dd ($this->precos);
       // here -  return error
           $this->calculos=$calculoSeguroService->getAll($this->precos->id, $this->atividadeCode);
    }
}
```php

@marsh hill what error are you seeing. ?

[marsh hill]

when i put this line

$this->calculos=$calculoSeguroService->getAll($this->precos->id

$this->precos->id //erro Property[id] does not exist on this collection instance

[thorny vessel]

Yes that’s correct. It is because you have a collection. The property id is on the model, which is inside the collection.

humm...

[thorny vessel]

The getPrecos() method returns a collection, so you need to get the item you want from it.

[marsh hill]

the fact of showing the model in the DD does not mean that it is accessible

[thorny vessel]

DD is showing a collection of models.

Collection != Model

Your method should either return one item, or you need to do first() on the collection to get the first item.

I need to learn how to interpret DD better

collection is eloquent's default return

[thorny vessel]

This is what you are seeing in the DD, https://laravel.com/docs/10.x/eloquent-collections

[thorny vessel]

No, only if eloquent is returning more than one model.

[marsh hill]

ok

ok, I'll read the documentation some more

[thorny vessel]

The solution is pretty simple. You just need to get the first item out of there. I’ve shown the method above.

But yes have a read. 👍

dd is showing you it's an array
the 0 is the index of the first element

a small detail that changes everything

public function getPrecos($atividadeCode)
{
return Preco::where('codigo', '=',$atividadeCode)->first();
}

It worked 🙂

thank you very much 🙂

Now

had used the get
return Preco::where('codigo', '=',$atividadeCode)->get();
